URL - <path>/jderest/tokenrequest

Data -  { "deviceName":"MyDevice", "username":"JDE", "password":"JDE" }

Curl Call request

curl -i -X POST -H "Content-Type:application/json" http://<path>/jderest/tokenrequest -eName":"MyDevice","username":"JDE","password":"JDE"}'

Response

{

  "message" : "Connection refused: connect",

  "exception" : "java.net.ConnectException",

  "timeStamp" : "2018-05-01:14.19.47"

}

Please suggest.
